For years, the best way to burn calories was through traditional interval training, a repetitive cycle of peaks and rests that turn the body on and off until exhaustion.

The problem is that these intervals are a shock to the system, making it impossible to maintain the intensity needed to see dramatic results.

Michelle's peak progressive intervals are smarter than that because their unique blend of cardio and strength moves are sequenced to trick your body into performing at a higher level. Without realizing it, each stage will take you a little further, push you a little harder and help you reach a higher level than you could with a traditional workout.
